Ukuthetha ngotyando lwe-laparoscopic, akumangalisi, ngokuqhelekileyo nge-2-3 1 cm yotyando oluncinci lokusika kwizigulana ezinotyando lomgodi, kwaye Isixhobo esilahlwayo se-laparoscopic biopsy kutyando lwe-laparoscopic eyona njongo kukumaleko wodonga lwesisu, ngaphandle kunye nomngxuma wesisu, vumela izixhobo zotyando ngomkhono wempahla yokugqobhoza ungene kumngxuma wesisu, Ukugqiba inkqubo yotyando kunye nokufezekisa injongo efanayo notyando oluvulekileyo lwesintu.
Isixhobo sokugqobhoza se-laparoscopic esilahlwayo senziwe nge-puncture cannula kunye ne-puncture core.Umsebenzi ophambili we-puncture kudonga lwesisu kunye ne-puncture cannula kwaye ushiye i-puncture cannula kudonga lwesisu.Owona msebenzi uphambili we-puncture cannula kukuvumela izixhobo ezahlukeneyo zotyando zingene kumngxuma wesisu, ukuze oogqirha bakwazi ukwenza utyando kwaye bagqibezele imisebenzi yotyando.
Ukusetyenziswa ngokuchanekileyo kwetrocar
1. Ukwahlula kabini icala lencam yepuncture
Ngokutsho kohlalutyo lwezibalo zengxelo, iingxaki ezininzi zokubhoboza umngxuma zibangelwa usulelo, ukopha, ukubhoboza umngxuma we-hernia kunye nomonakalo wezicubu, njl.
I-laparoscopic elahlayo enempahla yokugqobhoza engundoqo i-conical ecacileyo, akukho ndlela zokwahlula imela buthuntu, kusetyenziswa enye indlela yokusika, xa isinxibo sokugqobhoza singena kudonga lwesisu, ecaleni kwefayibha ukuya kwithishu kunye ne-vascular puncture core kude, umonakalo omncinci kudonga lwesisu kunye negazi. izitya, kunokuba ngekrele lokugqobhoza impahla yokusika malunga ne-40% yokwenzakala kwenwebu kunye nokunciphisa ngaphezulu kwe-80% yokwakheka komngxuma wokuhlatywa kwe-hernia, Ngokusebenzisa i-endoscopy, yonke inkqubo yokuhlatywa kodonga lwesisu inokulawulwa ngokuthe ngqo, ukuthintela umonakalo izicubu zesisu, ukugcina ixesha lokusebenza kunye nokunciphisa intlungu yokusebenza.
2. Umsonto we-barb wangaphandle wetyhubhu ye-sheath
Umsonto ohlabayo wangaphandle usetyenziselwa kumphezulu wetyhubhu ye-sheath yesixhobo sokuhlatywa kwe-laparoscopic elahlayo ukunyusa ukulungiswa kodonga lwesisu.Xa i-core puncture ikhutshwe, amandla anyuka, kwaye ukulungiswa kodonga lwesisu kunokuphuculwa malunga ne-90%.
3. Ukuvulwa kwe-45 ° bevel kwi-sheath tube ekupheleni
Ukuphela kwetyhubhu ye-sheath yesixhobo sokuhlatywa kwe-laparoscopic esilahlwayo savulwa nge-bevel ye-45 °, ukwenzela ukuba kube lula umboniso wokungena kwi-tube ye-sheath kwaye ushiye indawo yokusebenza kwesixhobo.
4. Gqibezela iimodeli kunye neenkcukacha
Isixhobo esilahlwayo sesibini se-laparoscopic puncture sineenkcazo ezahlukeneyo: i-diameter yangaphakathi 5.5mm, 10.5mm, 12.5mm, njl.
